SiC/SiCwaxay leedahay iska caabin kulayl aad u fiican waxayna bedeli doontaa superalloy codsiga aero-engine
Saamiga culeyska-sare ee culeyska waa yoolka matoorada-matoorada horumarsan. Si kastaba ha ahaatee, korodhka culeyska culeyska culeyska, heerkulka gelitaanka marawaxadaha ayaa sii kordhaya, iyo nidaamka walxaha superalloy ee jira way adag tahay in la buuxiyo shuruudaha matoorada-mashiinnada sare. Tusaale ahaan, heerkulka daloolka marawaxadaha ee matoorada jira ee leh saamiga riix-ilaa-miisaanka ee heerka 10 ayaa gaadhay 1500 ℃, halka celceliska heerkulka matoorada leh saamiga riix-ilaa-miisaanka ee 12 ~ 15 uu dhaafi doono 1800 ℃, taas oo ah aad uga fog heerkulka adeega ee superalloys iyo isku dhafka intermetallic.
Waqtigan xaadirka ah, superalloy-ku-saleysan nikkel oo leh iska caabbinta kulaylka ugu fiican waxay gaari kartaa oo keliya 1100 ℃. Heerkulka adeegga ee SiC/SiC waa la kordhin karaa ilaa 1650 ℃, kaas oo loo arko inuu yahay midka ugu habboon ee hawo-matoorka qaab dhismeedka kuleylka kuleylka ah.
Yurub iyo Maraykanka iyo dalalka kale ee hore u maray duulista.SiC/SiCwuxuu ahaa codsi wax ku ool ah iyo wax soo saarka ballaaran ee qaybaha aero-engine-ga, oo ay ku jiraan M53-2, M88, M88-2, F100, F119, EJ200, F414, F110, F136 iyo noocyada kale ee militariga / matoorada aero-madaniga ah; Codsiga qaybaha wareega ayaa weli ku jira marxaladda horumarinta iyo imtixaanka. Cilmi-baarista aasaasiga ah ee Shiinaha ayaa si tartiib tartiib ah u bilaabatay, waxaana jira farqi weyn oo u dhexeeya iyada iyo injineernimada cilmi-baarista ee dalalka shisheeye, laakiin sidoo kale waxay samaysay guulo.
Janaayo 2022, nooc cusub oo ah matrix dhoobo ah ayaa ah jaamacada farsamada gacanta ee waqooyi-galbeed iyadoo adeegsanaysa agabka gudaha si ay u dhisto mishiinka marawaxadaha hawada madal tijaabo ah, laakiin sidoo kale si kor loogu qaado iskudhafka matrix-ka dhoobada ah ee ka kooban qaybaha hawada aan duuliyaha lahayn (uav)/drone codsiga baaxadda weyn.
